Joint injuries can be serious, painful and debilitating. If this doesn’t go away you should probably see a doctor of physical therapist about it. You definitely shouldn’t lift any more weights until this blows over.

You say you’ve just started, so here’s a few good things to keep in mind:

Always rest if you overextend yourself. It’s not about doing it as often as possible. Ideally you should never do more than 2 sessions per week, and never less than three days apart. Even if you do more than that, try to space them out.

Remember that the muscle doesn’t grow while you’re lifting, it just swells a bit. The actual growth happens over 2-3 days after the session, and doing another one too early really messes it up.

Never, ever lift if your muscles still hurt.

Don’t just lift again and again. You can get more benefit if you do sets and take a rest and a drink after each one.

Do it properly. Talk to someone who knows weights, there will be such people at a gym or if you’re younger your PE teacher should know. Weights, more than most excercise, can badly injure you if done badly.
